Matebulo opangira zowotcherera amasintha momwe opanga zinthu amagwirira, kupeza, ndi kubwereza mbali zina - osagwirananso ndi diso, osakhalanso ndi kugwedezeka. Tawona masitolo akudula nthawi yokhazikitsira ndi 65% mutasintha kuchoka ku jigs kupita ku modular Welding fixture table machitidwe. Makasitomala m'modzi ku Changzhou amawotcherera mafelemu a chassis ofanana kwa zaka zitatu pogwiritsa ntchito mbale yoyambira imodzi ndi zida zosinthika - ziro zopatuka pazigawo 12,000.
Chifukwa chiyani kubwereza kumayambira patebulo - osati chowotcherera
Zolakwika zambiri zowotcherera zimayamba arc isanamenye. Gawo lina limasintha 0.3 mm panthawi yothirira. Chibwano cha vise chimavala mosagwirizana. Pansi pa nthaka imataya kusalala pambuyo pa matenthedwe asanu. Izi si "zolakwika za opareshoni." Ndi zolephera za dongosolo-ndipo zimaphatikizana ndi cholumikizira chilichonse.
A zoona Welding fixture table amathetsa izi pa maziko. Si mbale yachitsulo yokhala ndi mabowo. Ndi njira yolumikizirana yokhazikika ku ISO 2768-mK tolerances, yokhala ndi T-slots yotalikirana molunjika 50-mm, malo olimba olimba (HRC 58-62), ndi mphamvu yonyamula katundu imatsimikiziridwa pa DIN 53404. Timayesa tebulo lililonse pansi pa 300% potengera katundu wosasunthika. Izi zikutanthauza kuti tebulo la 1,200 kg limakhala ndi 3,600 kg popanda kupotoza koyezeka.
Kulephera kwenikweni kumachitika pamene ogwiritsa ntchito amanyalanyaza kukhazikika kwamphamvu. Kumangirira tebulo lokhala ndi chitsulo chochepa kwambiri cha 6-mm? Yembekezerani kutsika kwa 0.18 mm pansi pa 800 kg. Kuchiyika pazitsulo zazitsulo za 25-mm zokhala ndi ma bolt anayi a M16 opangidwa ndi 190 N·m? Kutembenuka kumatsika mpaka 0.02 mm. Gome silinama-njira yothandizira imatero.
Modular vs. fixed: Ndi chiyani chomwe chimapereka ROI m'masiku 90?
Ena amatsutsa zomangira zomangidwa mwamakonda zimamenya matebulo modulira molondola. Koma tidafufuza malo ogulitsa ntchito 17 apakati pa miyezi 18. Omwe amagwiritsa ntchito ma jigs okhazikika amakhala pafupifupi $4,200 pakupuma kwapachaka pa siteshoni-makamaka kuchokera pakuchedwa kukonzanso ndi kusungirako zinthu zambiri. Modular Welding fixture table ogwiritsa adawononga $ 1,100 pakukonzanso zida pachaka ndikubwezeretsanso maola 11 / sabata pamapulogalamu ndi nthawi yamakonzedwe.
Kusiyana kwagona pakutha kusintha. Dongosolo lokhazikika limagwiritsa ntchito zigawo zokhazikika: njanji za mbiri (20 × 20 mm, 30 × 30 mm, kapena 40 × 40 mm zotayira zotayidwa), zotsekera zotsekera ndi ± 0.02 mm kubwereza, ndi malo osintha mwachangu okhala ndi zikhomo zachitsulo zolimba (Ø6 mm, Ø8 mm, Ø10 mm). Mumapanga zida zatsopano mkati mwa mphindi 90 - osati masiku atatu.
Nazi zomwe zimagwira ntchito-ndi zomwe sizikugwira ntchito:
- Ntchito: Kugwiritsa ntchito mapini a dowel a Ø10 mm pamalo oyamba; kulumikiza mtedza wa T-slot wokhala ndi zomangira zocheperako (M6 × 12 mm) kupewa kusokonezedwa ndi njira zounikira loboti
- Zalephera: Kusanjikiza zigawo zitatu za adaputala mbale popanda recalibrating Z-axis datum; pogwiritsa ntchito zingwe za pulasitiki pazitsulo zotentha zotentha zopitirira 120 ° C
- Kunyalanyazidwa: Kupitiliza kuyika pansi - chotchinga chilichonse chiyenera kusunga ≤0.1 Ω kukana pa tebulo. Timayesa izi ndi Fluke 1625-2 tisanatumize
Botou Haijun Metal Products Co., Ltd. imapanga matebulo ake mozungulira izi. Kuyambira m’chaka cha 2010, mainjiniya athu akhazikitsa mayunitsi opitirira 2,300 m’madera osiyanasiyana ogulitsa magalimoto, opanga zipangizo zaulimi, ndi malo okonzera magalimoto a njanji—zonsezi zili mumzinda wa Botou, m’chigawo cha Hebei, kumene kutentha kumasinthasintha kuchoka pa −15°C kufika pa 42°C pachaka. Kukhazikika kwa kutentha sikoyenera. Zimamangidwa muzitsulo zochepetsera kupsinjika komanso kulipidwa kwa geometry ya slot.
Kukhazikitsa si pulagi-ndi-kusewera-ndipo ndiye mfundo yake
Mufunika konkire yokhazikika, osati malo ogulitsira a epoxy. Kuchuluka kwa slab: 150 mm. Kutalikirana kwa mipiringidzo: ≤200 mm pakati kupita pakati. Kuzama kwa bawuti ya nangula: ≥180 mm mu konkire yochiritsidwa (osati kutsanulira kobiriwira). Dumphani sitepe iliyonse, ndipo kulolera kwanu kwa 0.05 mm kumakhala 0.4 mm mkati mwa miyezi isanu ndi umodzi.
Timafunikira kuyanjanitsa kwa laser pakuyika komaliza-kugwiritsa ntchito Leica Geosystems LS15 rotary laser, osati mulingo wa mizimu. Chifukwa chiyani? Chifukwa mphamvu yokoka sikusamala za gulu lanu lololera. Kupendekeka kwa 0.1 ° kudutsa tebulo la 2,000 mm kumapanga kusiyana kwa 3.5 mm kutalika kumapeto. Ndikokwanira kusokoneza tracker ya robotic seam.
Mphamvu ndi maziko nazonso. Matebulo opangira zowotcherera amayenera kumangirizidwa ndi dothi lofanana ndi gwero lamagetsi. Palibe ndodo zosiyana. Osalowerera ndale. Njira imodzi yosalekeza-yotsimikiziridwa ndi megohmmeter pa 500 V DC. Timalemba zowerengera zonse zotsutsa mu lipoti la Commissioning. Makasitomala amene kudumpha izi amaona kuvala msanga pa mizere mizere ndi molakwika CNC kaimidwe.
Botou Haijun imapereka chithandizo chokwanira - osati zolemba zokha. Akatswiri athu amanyamula mikono yonyamula ya CMM kuti atsimikizire kusalala pambuyo poyika. Kulekerera kwa flatness ndi ≤0.08 mm kudera lililonse la 1,000 × 1,000 mm. Ngati sichikanika, timasintha ma shims kapena kubowolanso anangula-pamalo.
Kulondola si chinthu. Ndilo maziko.
A Welding fixture table sichimapangitsa welds kukhala wamphamvu. Zimawapangitsa kukhala odziwikiratu. Imatembenuza kusiyanasiyana kwamitundu kukhala kusinthasintha kolamuliridwa-osati lotale. Masitolo omwe amawatenga ngati zomangamanga-osati zida-onani mitengo yazitsulo ikutsika kuchokera pa 4.7% mpaka 0.9% mkati mwa miyezi inayi. Iwo amasiya kufunsa "Kodi tamva bwino?" ndikuyamba kufunsa "Kodi tingakweze bwanji?"
Kusinthako kumayamba ndi kusankha kwazinthu (zotsitsimula EN-GJL-250 chitsulo chotayira, osati chitsulo chowotcherera), kumapitilira ndi makina a metrology-grade (CNC-milled slots yomwe imasungidwa ku ± 0.015 mm), ndipo imatha ndi kutsimikizika kwadziko lenileni-osati zolemba za labu. Botou Haijun Metal Products Co., Ltd. amamanga malo ogulitsira, osati malo owonetsera. Tebulo lililonse limayenda ndi satifiketi yoyeserera, ma torque athunthu, komanso kuchuluka kwa kutentha komwe kumakhala ndi nyengo yanu.
Tsogolo ndi la opanga omwe amawotcherera kamodzi - ndikuwongolera. Osati omwe amawotcherera, kuyeza, kupera, kuwotcherera, ndi chiyembekezo. Gome lanu lotsatira siliyenera kukhala ndi magawo. Iyenera kutsimikizira zotsatira.
